Ah thats good to know. I normally advise people that Google wont even know you rooted or unlocked if you simply just unroot and lock the bootloader again.

Hello everyone, :confused:

I have a 16 GB rooted T-mobile Samsung Galaxy S III, I am currently running CM 10 Nightlies ROM. I love my phone, it is working fine, but I would like to know if there is a way that I can somehow enable the dalvik cache to save automatically on my external SD which is 32 GB or at least to automatically save the pictures and videos in there. I remember I used to do this on my HTC Wildfire S with an app called S2E but I tried downloading it for my SG3 and Its not available for it.

I am sure there has to be a way out there to do this, although I've been looking all over the place and I still cant't find a way to do this. I just really want to make the best out of my phone's internal memory and take advantage of my 32 GB SD card that is just sitting there in my phone doing nothing.

If anybody has an idea or knows I will be greatly appreciated.

Thanks
[T-Mobile, Samsung Galaxy SIII] Da Kine:
Wiping dalvik cache shouldnt even touch your SD card. So your videos and photos should be fine. If you really want to be safe, just save a copy of your photos and videos on your computer or laptop, or even on another SD card. Or you can just upload them on to drop box or Google drive.

what I am looking for is if I can move the dalvik cache and photos and videos to save automatically on my external memory so I have way more space on my internal memory, since I have lots of apps .

HTC Wildfire S Help

Maybe CM does not support it? Or try getting "cachesd" and using Terminal Emulator with the command: SU (hit enter) cachesd

But I have an Rooted HTC Wildfire S from MetroPCS, I'm running Android 2.3.4 on the stock ROM with unlocked bootloader. I installed S2E but the option to move Dalvik Cache to the SD Card is shaded out (Not usable) How do I change this?
[T-Mobile, Samsung Galaxy SIII] chucktdriscoll:
Having photos and videos save to external SD I can understand, but why would you want to move the dalvik-cache? Even if you have a large number of apps it's not going to be large enough to make much of a difference on an S3 (my phone with about 50 downloaded apps and the system apps has a dalvik-cache of about 60MB.)

I am on 4.2.2 and the bluetooth won't turn on. As soon as i click ON, it immediately goes back to OFF (in blink of an eye). Is it due to the well known wifi-bluetooth issue? It happened yesterday when wifi was off even. Restart is the only temporary cure as for now. Any suggestions?

I also have this issue but its fine once I reboot. Still annoying tho
[Nexus 4 Q&A, Help & Troubleshooting] moses992:
Same here. I dont know how Google released 4.2.2 without fixing a huge bug like this that affects daily use, its really annoying ;(.
[Nexus 4 Q&A, Help & Troubleshooting] pyrotenax:
Bluetooth is fine for me on 4.2.2
[Nexus 4 Q&A, Help & Troubleshooting] filthykid:
Exactly. Although a restarts fixes the issue temporarily but it's pretty annoying as bluetooth is used daily and that too quite a lot of times in a day, sometimes. So constant restart really isn't a cure. Anyhow, I was wondering it's just me and this youtube user lol.. but now I know it's kind of a known issue and hopefully Google will fix it, since they know the issues with BT/WiFi etc. But I heard they fixed it in 4.2.2 however, we are still getting it which means the issue hasn't been resolved completely.

Edit: I was using Juice Defender Ultimate earlier and the issue started happening right after a few days of the said app's. installation. Googled a bit and got to know JDU is the culprit. So I uninstalled it on Saturday. But issue still persists.
[Nexus 4 Q&A, Help & Troubleshooting] moses992:
Never had Juice Defender Ultimate installed on my phone,so thats definitely not the cause. However maybe another app is causing this ? Would be interesting if we could find out.

I am also glad im not the only one with this problem, but it seems like it isnt affecting a lot of devices .. I mean this thread is barely getting responses ? Anyway I hope this gets fixed soon.
[Nexus 4 Q&A, Help & Troubleshooting] carlosmg2:
I hardly ever use the BT, but the only 2 times I needed it, it happened the same to me. Never used juicedefender, unlocked bootloader + root only.

It's not a big issue for me... but IT IS an annoying issue

I had this for the first time today. The only app I have that might effect it is Qualcomm Battery Guru.

Hmmm.. I uninstalled JDU after reading this thread:

This Bluetooth not turning on issue is really annoying. Anyone has any news for it? No fix? Nothing?

I have to restarted my device several times in a day. And it extremely embarrassing when someone asks for a file transfer and you say him.. wait i need to restart the phone. BT isn't turning on :(:(:(:(
[Nexus 4 Q&A, Help & Troubleshooting] moses992:
I asked a friend of mine, who has a N4, about this and he said it never happened to him. It seems that not all devices are affected with this bug ? Could it be a hardware thing ?
[Nexus 4 Q&A, Help & Troubleshooting] Salty Wagyu:
Only had it happen once during the last three weeks so the issue is quite rare. Also had to reboot to fix.

You can leave Bluetooth enabled though, it doesn't drain battery whilst inactive.
[Nexus 4 Q&A, Help & Troubleshooting] kzoodroid:
Same here, have no issues. I did have issues with wifi not turning itself back on when I was using Qualcomm's Battery Guru. Are you using any type of battery saving app like Tasker? If you are try uninstalling it and see if that helps.
[Nexus 4 Q&A, Help & Troubleshooting] crownua6:
Experiencing the same issues :(
[Nexus 4 Q&A, Help & Troubleshooting] filthykid:
No. I don't use any battery saving app. I recently installed Battery Guru. But the issue was there even before installing it. The issue is there since the day I got my hands on the device. I seriously don't want to RMA as everything else is excellent in the device. Infact.. I seriously do not hear any buzzing sound from it.. even in a silent room. It was there in first few days but it was hardly audible. And now its gone. I have tried many times listening in a silent room but don't hear it anymore. So everything is perfect besides this BT bug :( I really really want a fix for it. No RMAing :(

Instead of rebooting the whole phone just turn airplane mode on then off
[Nexus 4 Q&A, Help & Troubleshooting] moses992:
I dont have any battery saving apps installed, never installed one too. Also the only workaround so far is to reboot, turning airplane mode on/off doesnt fix anything.
[Nexus 4 Q&A, Help & Troubleshooting] filthykid:
+1
[Nexus 4 Q&A, Help & Troubleshooting] filthykid:
It isn't related to the Network or Carrier etc. It's purely a software glitch.... that's why the whole phones needs to be rebooted.

I recently noticed after rebooting, the bluetooth is ON. This makes me think, while we are trying to turn it on and the button goes back to OFF.. the software is actually trying to signal the hardware to turn it on but somehow it isn't able to do so... that may be due to some wrong scripting. So, when we reboot the device, the BT is actually ON. It means the hardware had turned it on but software was not processing it's command properly.
[Nexus 4 Q&A, Help & Troubleshooting] subxero123:
I didn't say its a carrier problem, my friend has a nexus 4 and is Bluetooth wasnt working, a simple airplane toggle fixed it

Whatever works for you guys! :)
[Nexus 4 Q&A, Help & Troubleshooting] moses992:
Exactly my thoughts. When I reboot i often find my Bluetooth on .. Do you think that means it was actually on the whole time, while the software wasnt able to "communicate" with the hardware ? Could it be draining the battery too ?
[Nexus 4 Q&A, Help & Troubleshooting] filthykid:
^moses992.

Yes. Because sometimes I notice, whenever after this "incident", I turn my device on (i.e.: after some hours).. the BT is ON and the device's temperature shoots up from its normal temp. In fact, a couple of times it went up to the extent that device started stuttering and I placed it in freezer to cool down. It then became normal.

So, I figured out, if we don't restart the device the moment we get this ON/OFF error, the device might react weirdly due the war going on between software and hardware to whether turn the BT ON or OFF. (Which in real is ON but the software just doesn't let it show up).

Bluetooth is causing so many freakin issues, don't really know which one to report lol. First this issue... Then i noticed i can't use a Bluetooth headset when Wi-Fi is on. Then i noticed at my workplace, where the strength of signals is a LITTLE weak... Over there my phone just refused me to use the Bluetooth headset.. I couldn't hear nothing at all (not even the call tone/ringer) and same was the response of the person at the other end.. even the Wi-Fi was off. I already have starred this complaint on Google's page but the complaint is registered by very limited people. I would request other people to help us by complaining this bug... no matter you don't have that problem. Just help some bros. :-/

The last couple of times I used bluetooth it turned on instantly and I had no problems. So I thought Id check this thread and give you a little update but seems like you beat me to it ^^`.

I wonder if we just got lucky or what,

it makes no sense for the issue to just disappear like that(not that im not happy :p). Ill give it a week and report my findings to you.
[Nexus 4 Q&A, Help & Troubleshooting] filthykid:
Haha.. Yeah seriously, I wonder how come the issue resovled all by itself? I mean I did not even get any software update. Even my colleague who has seen me suffer from the issue many times (as we transfer apps and wallpapers thru BT) was shocked that how come the issue resolved without any update.. lol..

I know the people who never had this issue would say to us: Aaaah noobs.. placebo effect. But NO, we literally encountered this frustating issue for quite a while.

I am really happy that it doesn't get stuck now, however, when transferring files from Computer, it mostly display an error like: The connection encountered a problem and blah blah.. and the transfer stops :(
[Nexus 4 Q&A, Help & Troubleshooting] Headcase_Fargone:
Still running into a myriad of bluetooth issues with this phone.

I have to keep bluetooth turned on at all times because I can't turn it back on without a reboot if it's off.

Bluetooth refuses to connect to other devices 90% of the time. Wifi being on (connected or no) seems to cause this issue more frequently but is not a prerequisite.

I've found that if I reboot the phone when I get into the car it will connect to my car's bluetooth upon booting 100% of the time. If I power cycle my car's bluetooth device the phone will immediately connect ~75% of the time, regardless of it refusing to before cycling the other device.
[Nexus 4 Q&A, Help & Troubleshooting] mrg2003:
BT won't turn on after turning off until reboot

What I don't like about the BT setting is the phone doesn't remember the bt/handset preference. when I answer a call, and select earpiece, I'd like it to remember it until I change it, but each time it goes back to headset.

[Nexus 4 Q&A, Help & Troubleshooting] vjovanovic1:
I get this BT issue from time to time. What I've noticed is that I usually get the problem when my WiFi was left on for the whole day (e.g. during workhours). So, when I start home, I turn the WiFi off and try to turn the BT on, but it doesn't turn on. In that case, I reboot the phone, and it allways wakes up with the BT turned on.

I haven't noticed the BT issue if the WiFi was not turned on previously for a prolonged period of time.
[Nexus 4 Q&A, Help & Troubleshooting] Headcase_Fargone:

[Nexus 4 Q&A, Help & Troubleshooting] KiNG OMaR:
I am pretty sure every Nexus 4 has this issue. Some people, like myself, use bluetooth religiously throughout the day and we toggle it on and off, so we notice that sometimes it refuses to turn on without a reboot. Some people don't toggle bluetooth as often and either leave it on or off all the time.

The problem has persisted through multiple rom/kernel combos, including stock 4.2.2
[Nexus 4 Q&A, Help & Troubleshooting] kishke:
Not all nexus 4 suffer from it. Me and my gf have both a N4, same rom+kernel, I used bluetooth every time I drive and it happens a lot. She doesn't use it but whenever I grab her device and check to see if bluetooth can be toggled it toggles.

Either some devices are affected and some aren't or it has to do with using bluetooth a lot.

P.S. I'm not toggling bluetooth manually, I'm using tasker to do it, maybe it has something to do with it and maybe not.
[Nexus 4 Q&A, Help & Troubleshooting] moses992:
Well i do not use bluetooth alot, in fact i rarely use it! But i certainly do have this issue(i keep bluetooth off all the time, sometimes i toggle it on/off just to try and figure out when or what influences this glitch).

If some N4s dont have this issue then im afraid its more hardware related ? And that we just have defective devices ?

Anyway, i really hope its a software glitch and that we'll get a fix in the next update(hopefully in a couple of days!).

[Nexus 4 Q&A, Help & Troubleshooting] Viewmax:
Do you have option to uninstall Llama entirely and test without it for a while? I'm not saying that there is problem with Llama, but seems only "in cooperation" with automated software (such as Tasker, Llama and others) bug could be reproduced.
[Nexus 4 Q&A, Help & Troubleshooting] WibblyW:
I'm afraid not. I use Llama for too much other stuff, and just leave Bluetooth on now.
[Nexus 4 Q&A, Help & Troubleshooting] maigre:
You can just exit Llama to test that way. Or you can backup all your profiles, etc., uninstall, experiment with bluetooth, reinstall and restore the backup.

My problem was that bluetooth and wifi don't always play nice together. Sometimes, I have the bluetooth problem, but more recently, when BT is turned on, I've had problems turning wifi off when I'm out of range of the locations where I use it. I turn it off, but it turns right back on, just like for some, including me on occasion, when I try to turn BT on, it turns right back off again.

There are times when all this behaves as it should. But mostly, it doesn't.
